The cause of the creases above your eyelids comes from a combination of decreasing elasticity of the skin of the eyelid and a slight lowering of the brow which happens to everyone. As the skin ages, it gets thinner because of loss of collagen and less effective elastin fibers. The skin begins to droop. Added to that is that there is only one muscle that elevates the eyebrow and seven muscles that cause the eyebrows to descend. Your blue eyes, that by definition are more sensitive to sunlight, cause more wincing when exposed to bright lights or sunlight. The normal progression of those two events causes the apparent excess skin over your eyelids. The correction may be a simple excision of a tiny strip of skin, or a brow pexy or lift if necessary. Care must be taken to prevent too much elevation since you have more prominent projection of your eyeballs as compared to someone who has deeper set eyes, If the brows are elevated too much or more skin is excised than necessary, you may not be able to completely close your eyelids which leads to dry eyes. A complete evaluation is necessary to decide what your best option is. John Standefer MD
